“I’m almost convinced that this new Technorati Tags thing is important, but I’m 100% convinced that I don’t understand where it’s going or what the implications are. Which is OK, because I suspect nobody else does either. (…) I’ve spent a lot of time thinking about metadata and have written on the subject; the most important conclusion was: There is no cheap metadata. I haven’t seen anything to make me change my mind.” (Tim Bray – ongoing)
